TRAIN-PIPE ANCHOR.

To all whom it may concern:

. Be it known that I, RICHARD WVEBB BURNETT, a citizen of the UnitedStates, residing at the city of Montreal, Province of Quebec, Dominionof Canada, have invented certain new and useful Improvements inTrain-Pipe Anchors; and I do hereby declare that the following is afull, clear, and exact description of the same.

This invention relates particularly to train pipe anchors adapted to berigidly secured to a member of the substructure and have the train pipelocated therein. Heretofore with devices of this nature it has not beenpossible to lock the pipe without the necessity of operating first atone side of the member and then at the other side thereof, or ininstances where, the center sill is used as a member for attachment thelock could not be got at readily after it was driven.

The object of the present invention is to overcome these ditlicultiesand provide a train pipe anchor which may be rigidly connected to amember of the substructure of the car and contain a locking devicecapable of having the pipe locked therein and at the same time keep thelocking device exposed under all conditions; a further object being toprovide an anchor which will more rigidly lock the pipe againstdisplacement therein.

The invention may be said to consist particularly of the construction,particular arrangement, and combination of parts hereinafter describedand pointed out in the claims.

For full comprehension, however, of my invention reference must be hadto the accompanying drawings forming a part of this specification inwhich similar reference characters indicate the same parts, and wherein:

Figure 1 is a face view of my improved train pipe anchor the train pipebeing illustrated in transverse sectional view; Fig. 2 is a sideelevation thereof; Fig. 3 is a vertical sectional view taken on line A BFig. 1; Fig. l is a face view of a modified form drawn to a smallerscale; and Fig. 5 is a similar view to Fig. 3 of the modification.

According to my invention the anchor member is preferably made ofmalleable iron and consists of a horizontal boss 0 through which thetrain pipe passes, a pair of perforated lugs aZ extending laterally fromone end of such boss and a key guide Specification of Letters LPatent.

rect thrust the anchor is caused to bite and consequently more rigidlyhold the pipe.

This effected by the lower half of the opening 7; being formedconcentrically with the boss, the center on in the embodimentillustrated being on a line m with the attachment holes a through thelugs although the attachment portions of the anchor may be formed toextend to any point above or below or to one side or the other of thepoints of attachment shown. In this embodiment of the invent-ion thelower half of the wall of the opening is formed with a pair of spacedconcentric inward extensions p p separated by a pipe clearance space .9;the upper half of the opening being of the same radius as the space 8and its center tis placed a short distance above the center 47?), thusproviding ample clearance for the upper half of the pipe.

The key indicated at n is tapered and of greater length than thekey-way.

The pipe indicated at o bears on the rests p p and when the key isdriven into the guide it slides against the upper wall of the guide andbites into the upper surface of the pipe. In order to anchor a pipe tothe cen ter sill through which it is the custom to pass it obliquely,the anchor is constructed with a horizontally elongated opening 2sufficiently greater in length than the diameter of the pipe to permitof considerable lateral play during the initial fitting of the anchor tothe sill. In this form the spaced pipe rests p p are dispensed with, butthe vertical measurement of the opening is still made greater than thediameter of the pipe, and the clearance is taken up by the key.

It will be observed particularly in Fig. 2 that the key-guide is offsetoutwardly from the attachment lugs, which has the advantage offacilitating the driving of the key and keeping both protruding endsexposed after it has been driven, thus enabling the small end or bothends to be bent for locking purposes. A further advantage of thisconstruction is that as the key lies transversely to the pipe thebearing point is reduced to a minimum and the biting action is moreeffective Whether the rests p p are employed or not. In the case of theneedle beam anchor the key is caused to bear in the same transverseplane as the rests p p thereby securing an efiective coaction of theseparts in rigidly securing the pipe against the direct end thrust towhich it is subjected and as the anchor is firmly clamped in place bybolts a: or the like, the anchorin of the pipe is secure and durable.hat I claim is as follows.:

1. A train pipe anchor comprising a member having a train pipe openingtherethrough, a vertical extension at the forward end of the member andhaving a horizontal key-way therethrough disposed at right angles to theopening, attachment means for the member and a tapered key of greaterlength than the key-way for the purpose of having its smaller end bentto lock such key against displacement in the key-way.

2. A train pipe anchor comprising a member having a train pipe openingtherethrough, a vertical extension at the forward end of the member andhaving a horizontal key-way therethrough disposed at right angles to theopening, a pair of alined horizontal attachment lugs upon the rear endof the member and a tapered key of greater length than the key-way forthe urpose of having its smaller end bent to loc such key againstdisplacement in the key-way.

3. A train pipe anchor comprising a member. having a train pipeopeningthere- RICHARD WEBB BURNETT.
